    It is not possible. They are made exclusively for each network.

    I just read a tread with a success full sex change from CDMA to GSM. You have to ghange the firmware to the unlocked GSM version and it should work.

    You would also need to change out the radio hardware
    Treo 600 > Treo 650 > Treo 700p > Treo 700wx -> Mogul -> Touch Pro
    You may like to flash, but your phone shouldn't. LED Killer

    If you open your Treo there actually is a module that you can remove that is the radio hardware. This module is actually seated in a connector and can be removed very easily without any soldering. I'm presuming that maybe if you get a GSM module and flash the unit to a GSM firmware you should be able to use the device without destroying it.
